Q. What is it about the brains of people who sell cars? I hate the games, and negotiations, and being treated like I don't even have a brain simply because I'm female! If only I could purchase a car without having to deal with a salesperson! What do you do?

Q. My 5-year-old son has not yet selected a dominant hand. Several individuals have made suggestions for strategies to force him to select one, and to develop his "dominant hemisphere." My brother is ambidextrous and I wonder about the wisdom of their advice.

Q. In an attempt to force him to become right-handed, my husband’s left hand was tied behind his back using a stout string that was attached to his belt. He does everything right-handed and hardly uses his left hand at all. Unfortunately, he continues to stutter and seems to become anxious easily. Do you have any comments?

Q. Whenever I mention intuition, someone in my family typically rolls his/her eyes and mumbles, "Yeah, right. Dream on." Does intuition really exist as a brain function, or is it just a figment of someone’s imagination?

Q. My boss tends to say "no" to most suggestions or requests I make. I've never thought of her as particularly negative or vindictive but this is getting ridiculous. I'm curious to know if you think this is a "brain thing."

Q. What do you say to people who ask "How does brain dominance theory sit with personality theory that I already understand?" I can't resolve it in my own brain because they seem to be two different models. Personality theory says "you can adapt" while brain dominance theory says "you have an innate preference."

Q. I’ve heard you speak about the importance of using positive words so all three brain layers can perceive them in a one-step process, but the Ten Commandments are negative. What do you have to say about that?
